Error message

Unknown region: ${region}

What it means

InvalidParameterError thrown by the Yahoo news provider handler when ctx.req.param('region') is not 'hk' or 'tw'. This route filters a region's archive by a specific providerId (e.g. yahoo_movies_hk_660), which is a HK/TW-only concept, so other regions are rejected before getProviderList/getArchive run.

\`ProviderId\`

除了可以通过路由 "新聞來源列表" 获得外，也可通过 hk.news.yahoo.com/archive 和 tw\\.news.yahoo.com/archive 选择 "新闻来源" 后通过页面 Url 来获得。

例如 hk.news.yahoo.com/yahoo\\_movies\\_hk\\_660-- 所有分類 /archive, \`yahoo_movies_hk_660\` 就是 ProviderId 。`,

Solutions

1. Use 'hk' or 'tw' as the region segment.
2. Obtain a valid providerId from the provider-helper route (/yahoo/news/provider-list/hk) or from the archive page URL on hk/tw.news.yahoo.com.

function requireHkTwRegion(region: string) {
    if (!['hk', 'tw'].includes(region)) {
        throw new InvalidParameterError(`Unknown region: ${region}. Use hk or tw.`);
    }
}

function isHkTwRegion(value: string): value is 'hk' | 'tw' {
    return value === 'hk' || value === 'tw';
}

When it happens

Trigger: A request to /yahoo/news/provider/:region/:providerId with region outside hk/tw. The guard fires immediately after destructuring {region, providerId}.

Common situations: Caller used a US/other region with a providerId; assumed the provider concept is global; typo.
